The Java Algebra System (JAS) is an object oriented, type safe, multi-threaded approach to computer algebra. JAS provides a well designed software library using generic types for algebraic computations implemented in the Java programming language. The library can be used as any other Java software package, or it can be used interactively or interpreted through a Jython or JRuby front end. The focus at the moment is on commutative and solvable polynomials, power-series, multivariate polynomial factorization, Gröbner bases, and applications.
Ruzzle Solver PRO is an offline solver (aka cheater) for Ruzzle puzzles. It aims to be usable, fast, and easy to extend and improve for both users and developers thanks to a sensible and modular design. It allows you to add, replace, or update the dictionaries and the score tables, thus supporting an arbitrary number of languages.
The Shepherd Project is a software framework to support capture-mark-recapture (CMR) studies. CMR is a core technique used in the analysis and management of wildlife populations. The Shepherd Project promotes non-invasive "virtual tagging" mark-recapture techniques (e.g., photo-identification via natural coat/skin coloration instead of physical tags attached to animals) to protect both animals and researchers in population studies. The aim of the Shepherd Project is to aid researchers in obtaining and managing CMR data to better understand and manage animal populations. The Shepherd Project is most successfully used as a collaborative, public-facing Web site, allowing members of the research community to collaborate and analyze data "behind the scenes" (with login access) and allowing members of the public to collect data as "citizen scientists" and submit it through submission forms.
Cysphere is an integrated social networking server for smaller virtual communities. It provides a private mailbox, public and private discussion forums, and simple file sharing, and makes it as simple as possible for users to communicate over the Web in a secure way. It includes an embedded Web server and SQL database and requires no installation or maintenance.
